Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

The shape memory device according to one embodiment can be commonly applied to a cover for a vehicle seat, a seat cushion for a chair, and a mattress. For the sake of convenience, the configuration related to the cover for a vehicle seat, the seat cushion for a chair, and the mattress will be described, without separately explaining the shape memory device.

FIG. 1 is a perspective view of a cover for a vehicle seat according to an embodiment of the present invention, FIG. 2 is a configuration diagram of a shape memory device according to a first embodiment applied to FIG. 1, and FIG. 3 is a partial plan view of FIG. 1 .

1 to 3, a cover for a vehicle seat of an embodiment is formed so as to be installed on a seat (not shown) of a vehicle. Further, the shape memory device 1 of the first embodiment is formed so as to be applicable to a cover for a vehicle seat. That is, the cover for a vehicle seat of the embodiment includes the shape memory device 1 of the first embodiment.

The shape memory device 1 of the first embodiment includes a cushion region portion 10, a valve 20, and a control portion 30. [ The cushion area section 10 is divided into a plurality of parts so as to partially receive the body weight and the body shape of the user and to be deformed and retained corresponding to the body weight and the body shape.

The valve 20 is connected to each cushion area section 10 so as to independently control the flow of air from the outside to the cushion area section 10 or from the cushion area section 10 to the outside. That is, the valve 20 regulates and interrupts the amount of air held in the cushion region 10.

The control unit 30 is configured to receive a user's use signal and to control the valve 20 independently. The control unit 30 controls the valve 20 to enable the cushion zone 10 to be deformed and to maintain the deformed condition of the cushion zone 10.

For example, the control unit 30 is connected to the operation switch 40 operated by the user, receives the use signal according to the operation of the operation switch 40, opens the valve 20 according to the use signal, The operation of the timer 31 causes the air in the cushion area 10 to be discharged for a preset time and then closes the valve 20. [

The air in the cushion area 10 is discharged by a predetermined amount of time while the valve 20 is open. Thus, the cushion area section 10 is deformed to a shape and pressure corresponding to the body weight and the body shape of the user, and remains in a deformed state.

When the shape memory device 1 is applied to a cover for a vehicle seat, the control unit 30 is incorporated in a control device (not shown) of the vehicle, and the operation switch 40 is replaced with a start switch (not shown) 30).

At this time, the control unit 30 receives the start signal of the start switch operated by the user, opens the valve 20 according to the start signal, and operates the built-in timer 31 to set the valve 20 Closing.

That is, in the cover for the vehicle seat, the ignition switch operates as the operation switch 40, and the start signal operates as the user's use signal. Therefore, the shape memory device 1 is operated simultaneously with the operation of the ignition switch so that the cushion region portion 10 is deformed and maintained and controlled so as to correspond to the body weight and the body shape of the user within the set time.

The cushion area section 10 has a plurality of cells 100 isolated from neighboring other cushion area sections and connected to the air passage P in each cushion area section 10. [ The plurality of cells 100 are configured to provide comfort to the user by deforming as air flows in and out according to the weight and body type of the user.

In one example, in the cover for a vehicle seat, the cushion area section 10 includes a front left area FL, a front right area FR, a left front area FL, A rear left area RL and a rear right area RR.

The valve 20 includes a first solenoid valve SV1 which is independently connected to and controlled by the front left region FL, the front right region FR, the rear left region RL and the rear right region RR, A valve SV2, a third solenoid valve SV3, and a fourth solenoid valve SV4.

The first solenoid valve SV1, the second solenoid valve SV2, the third solenoid valve SV3 and the fourth solenoid valve SV4 are connected to the control unit 30 and are respectively controlled to control the front left area FL, The front right region FR, the rear left region RL and the rear right region RR are independently controlled to correspond to body weight and body shape at each portion.

Thus, the front left region FL, the front right region FR, the rear left region RL and the rear right region RR correspond to the user's body weight and body shape (e.g., the left and right thighs of the leg and the left, Corresponding to the right side).

The first solenoid valve SV1, the second solenoid valve SV2, the third solenoid valve SV3 and the fourth solenoid valve SV4 are disposed at positions and intensities in which the body weight and the body shape are concentrated or dispersed, And may be opened and closed for another time with a parallax according to each other.

FIG. 4 is an exploded perspective view of a cell applied to the shape memory device of FIGS. 1 and 3, and FIG. 5 is a cross-sectional view taken along line V-V of FIG.

4 and 5, the cushion area part 10 (FL, FR, RF, RR) and the cell 100 include a cushion member 101 and a cushion member 101 which are deformed according to the body weight and body shape of the user And includes a bottom receiving member 102 and a lid receiving member 103 for supporting and receiving a liquid.

The floor receiving member 102 supports the lower surface of the cushion member 101 and has a flexibility by receiving a part of the side surface of the cushion member 101. The lid accommodating member 103 supports the upper surface of the cushion member 101 and has the flexibility to receive the remaining part of the side surface of the cushion member 101. [

The bottom receiving member 102 and the lid receiving member 103 are attached to each other in an airtight manner. The floor and lid receiving members 102 and 103 connect the adjacent cells 100 in the same cushion area section 10 (FL, FR, RF, RR) with air passages P, 10; FL, FR, RF, RR).

4 and 5, the cushion member 101 includes a lower cushion member 111 accommodated in the floor receiving member 102 and a lower cushion member 111 disposed on the lower cushion member 111 and accommodated in the lid accommodating member 103 And an upper cushion material 112. For example, the cushion member 101 may be formed of a memory foam, a latex, and a sponge.

The lower and upper cushioning members 111 and 112 are separated from each other and are stacked and closely contacted with each other in the vertical direction when the body weight and the body shape of the user act on the cushion area unit 10 (FL, FR, RF, RR) Are accommodated in the floor and lid accommodation members (102, 103), respectively, so that they can be stepwise deformed in the height direction according to the body weight and the body shape.

That is, the lower and upper cushioning materials 111 and 112 disperse compressive deformation in the cushion area part 10 (FL, FR, RF, RR) and the cell 100 to prevent intensive compressive deformation at the upper part or the lower part, After release, it is decompressed at a plurality of positions at the same time to enable stable restoration.

In this embodiment, the upper and lower cushioning materials 111 and 112 may be made of the same material. Although not shown, the lower and upper cushioning materials may be formed of different materials so that the compression deformation may be derived differently from the lower side or the upper side, if necessary.

In this embodiment, two cushion members 101 are illustrated. Although not shown, the cushion members may be formed in a larger number and may be formed of different materials so as to induce compression deformation and decompression in various combinations in the height direction.

In the cell 100, the lower cushion material 111 has a plurality of protrusions 113 on the lower side. The bottom receiving member 102 is formed to correspond to the protrusion 113 to receive the lower cushion material 111 and the projection 113 in a hermetic manner.

The corresponding structure of the projections 113 and the bottom receiving member 102 of the lower cushion material 111 can improve the mutual frictional force between the floor receiving member 102 and the vehicle seat when the cover for the vehicle seat of the embodiment is installed on the vehicle seat. So that the cover for the vehicle seat can be effectively fixed.

In the cell 100, the lower and upper cushion materials 111 and 112 form a space SP between the floor and the lid-accommodating members 102 and 103. The space SP is connected to the air passage P to enable air to flow between the cells 100 and to store the air together with the lower and upper cushion materials 111 and 112.

That is, the space SP is connected to the air passage P in the front left area FL, the space SP is connected to the air passage P in the front right area FR, The space SP is connected to the air passage P and the space SP is connected to the air passage P in the rear right region RR.

The first solenoid valve SV1 is connected to the spaces SP in the front left area FL by an air passage P to control the inflow and outflow of air and the second solenoid valve SV2 controls the front right area FR to air passages P to control the inflow and outflow of air.

The third solenoid valve SV3 is connected to the spaces SP in the rear left area RL by an air passage P to control the inflow and outflow of air and the fourth solenoid valve SV4 controls the air in the rear right area RR to air passages P to control the inflow and outflow of air.

The upper and lower cushioning materials 111 and 112 in the cell 100 are configured so that when the body weight and the body shape of the user are compressed and compressed, the amount of air in the cell 100 is adjusted while limiting the discharge of air, Thereby forming and maintaining the same.

Accordingly, the plurality of cells 100 housing the upper and lower cushioning members 111 and 112 can maintain a shape corresponding to body weight and body shape at each position, thereby providing a user with stability and comfort.

Fig. 6 is a cross-sectional view showing a modified example of a cell applied to the shape memory device of Figs. 1 and 3. Fig. 6, in the cushion member 202 of the cell 200 of the shape memory device of the modification, the lower cushion material 211 and the upper cushion material 212 are formed of a flexible material S on the lower side, Is formed of a material (H). For example, the rigid material H may be formed of a flexible synthetic resin.

When the user's body weight and body shape act on the cell 200, the rigid material H on the upper side expands and disperses the body weight over the entire area of the cell 200. [ The flexible material (S) on the lower side is flexibly compressed by receiving the dispersed weight and body shape.

The lower cushioning member 211 and the upper cushioning member 212 can be compressed and decompressed more flexibly by expanding and distributing the weight by dividing the lower portion and the upper portion of the upper portion by the rigid material H and the flexible material S, respectively .

In other words, the rigid material H on the upper side of the upper cushion material 212 firstly broadens and disperses the body weight and the body shape to the entire area of the cell 200, while the lower flexible material S receives the expanded and dispersed body weight and body shape, It is compressed primarily.

The rigid material H from the upper side of the lower cushion material 211 is secondarily expanded and dispersed in the entire area of the cell 200 with the body weight and the body shape and the lower flexible material S receives the expanded and dispersed weight, Compressed by a car.

The structure in which the rigid material H and the flexible material S of the upper cushioning materials 211 and 212 are stacked repeatedly in the up and down direction in which the weight of the upper cushioning material 211 and 212 is absorbed is intensively compressively deformed in the upper portion or the lower portion of the cell 200 And enables stable restoration after weight loss, i.e., decompression.

Hereinafter, various embodiments of the present invention will be described. The same configurations are omitted in comparison with the first embodiment and the previously described embodiments, and different configurations will be described.

FIG. 7 is a perspective view of a cover for a vehicle seat according to another embodiment of the present invention, and FIG. 8 is a configuration diagram of a shape memory device according to a second embodiment applied to FIG.

Referring to Figs. 7 and 8, the shape memory device 2 of the second embodiment is formed so as to be applicable to a cover for a vehicle seat. The shape memory device 2 includes sensors 50 provided in each of the cushion area sections FL, FR, RF and RR to generate a use signal and connected to the control section 230 in parallel.

The control unit 230 is connected to the sensors 50 operated by the user's body weight to receive a use signal according to the operation of the sensors 50 and to control the cushion area 10 to close the valve 20 after the signals of the sensors 50 are stable.

For example, the stable signal value is stored in a database in the control unit 230, and the control unit 230 compares the stored signal value with the signal value according to the operation of the sensors 50 to open / close the valve 20 .

While the valve 20 is open, the air in the cushion area 10 is discharged as much as the body weight of the user. Thus, the cushion area section 10 is deformed to a shape and pressure corresponding to the body weight and the body shape of the user, and remains in a deformed state.

The sensors 50 are formed by cutting the silver halide fabric 21 or 22 into a plurality of halves and are connected to the control unit 230 by the terminal wire 23 so that the pressure applied to the silver halide fabrics 21 and 22 (R) according to the change of the reference voltage (Pr) is measured and applied to the controller (230).

The silver halide fabrics 21 and 22 reduce the overall thickness of the shape memory device 2 by forming the thickness of the sensors 50 to be thin. Therefore, the use and handling of the shape memory device 2 and the cover for a vehicle seat to which the shape memory device 2 is applied can be facilitated.

In one embodiment, the sensor 50 is formed of two layers of silver fabric 21,22. Since the two layers of silver thread 21 and 22 form a structure in which the resistance wires are connected in parallel, when the same pressure Pr acts on the two layers of silver thread 21 and 22, (R) can be further amplified.

Therefore, the change of the resistance value R may be larger depending on the body weight and body type of the user. That is, the silver thread fabrics 21 and 22 may be formed in two or more layers. The plurality of silver thread fabrics 21 and 22 may not significantly increase the thickness of the shape memory device 2. [ In addition, when the shape memory device 2 supports the weight and the body shape of the user, the thread fabrics 21 and 22 can minimize the inconvenience to the user due to flexibility.

On the other hand, the sensors 50 are configured to detect independently in response to body weight and body shape in each of the front left region FL, the front right region FR, the rear left region RL and the rear right region RR, A first sensor S1, a second sensor S2, a third sensor S3 and a fourth sensor S4.

That is, the front left region FL, the front right region FR, the rear left region RL and the rear right region RR correspond to the body weight and body shape of the user (for example, the left and right femoral regions of the legs and the left, Corresponding to the right side). Therefore, users can feel stability and comfort.

The cushion zone 310 includes a front zone FA and a rear zone RA that define the front and rear sides of the seat cushion. The sensors 350 may include a first sensor S1 and a second sensor S2 provided in each zone so as to independently detect the front area FA and the rear area RA in correspondence to the body weight and the body shape in each part .

The first solenoid valve SV1 and the second solenoid valve SV2 are connected to the control unit 330 and are respectively controlled so that the front area FA and the rear area RA are independently controlled to correspond to body weight and body shape .

The control unit 330 includes a first solenoid valve SV1 and a second solenoid valve SV2 that are independently connected to the forward area FA and the rearward area RA according to the sensing signals of the first sensor S1 and the second sensor S2, Thereby controlling the valve SV2 independently.

I.e. the front region FA and the rear region RA are deformed and deformed so as to correspond to the body weight and body shape of the user (e.g., corresponding to the thighs and hips of the legs). Therefore, users can feel stability and comfort.

14, the controller 30 opens the first solenoid valve SV1 for a long time according to the detection signals of the first sensor S1 and the second sensor S2, and the second solenoid valve SV2 Can be opened for a short time.
